What Is cataract? A cataract occurs when the natural lens of the eye becomes opaque, often due to aging, high blood sugar, ocular trauma, specific medications, or prolonged sunlight exposure. Signs may include unclear eyesight, glare and halos around lights, faded colours, frequent changes in spectacles, and difficulty with night https://www.deviantart.com/eyeheal/journal/Clear-Vision-Starts-Here-Advanced-Cataract-1332641534
